I have heard from our moderator, and from several others.  Apparently
most receipients also are experiencing duplication.  Here's the gist of
our exchange.  Does anyone have an address of a network "guru" who
should be considering fixing whatever bug is at work here?

    You are not on the info-apple list twice; I just checked.

    There is no "bureaucracy" of list maintenance.  This is merely a
service provided on my own time and on a taxpayer-supported computer.
Use of a government computer is justified by the large number of Apple
computers at use in Army laboratories and offices.

    Duplicate messages often occur when a relaying host begins
"burping" for some reason.  Another cause of duplicate messages can be
found in the Internet/Usenet gateway where the newsgroup comp.sys.apple
and the mailing list Info-Apple interchange traffic.

My reply:

Thanks for checking, and for the prompt response.  I can survive
the deja vu experience.  I just received two mailings this morning
which are duplicates of messages from last Sunday.  Undoubtedly
the whole mail-list capacity over multiple networks is a complicated
software process.  If the unwanted duplicate problem exists on your
list, then it probably occurs for most others.  The total redundant
traffic on the nets must be substantial.  Given the concerns with
network message loads I've been reading about, it would seem a good
idea if someone who knows how the process works looked into fixing
it... I wonder who that might be?

I appreciate the info-apple service; it's very interesting.
